Description

Botanical designation: Chrysanthemum×morifolium Ramat.

Cultivar denomination: ‘Zanmuglow’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of chrysanthemum plant, botanically known as Chrysanthemum×morifolium Ramat., commercially known as a garden mum, and hereinafter referred to by the cultivar denomination ‘Zanmuglow’. ‘Zanmuglow’ is a product of a breeding and selection program for outdoor pot mums (garden mums) which had the objective of creating new cultivars with a double type inflorescence, a natural season flower date around August 24 (week 35), blooming for a period of 5 weeks. ‘Zanmuglow’ is a seedling resulting from a cross of the female parent id 9288 with the male parent id 15007. Plants of the new cultivar ‘Zanmuglow’ differ from plants of the female parent in color of the ray florets. Color of the ray florets of the female parent is yellow, while it is white in the seedling. Plants of the new cultivar ‘Zanmuglow’ differ from plants of the male parent in plant size. Plants of the male parent are smaller than those of the seedling.

The new and distinct cultivar was discovered and selected as a flowering plant by Wilhelmus Bernardus Blom on a cultivated field in Rijsenhout, The Netherlands in 2005. The first act of asexual production of ‘Zanmuglow’ was accomplished when vegetative cuttings from the initial selection in 2005 were propagated further in a controlled environment in Rijsenhout, The Netherlands. The new cultivar has been found to retain its distinctive characteristics through successive propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum is shown in the accompanying drawings, the color being as nearly true as possible with color photographs of this type.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows the various stages of bloom of the new cultivar.

FIG. 3 shows the various stages of foliage of the new cultivar.

 DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants grown out door in Rijsenhout, The Netherlands under natural day length and temperature and planted in week 23 in 2009. The natural blooming date of this crop was August 24 (week 35). The average height of the plants was 23 cm. No growth retardants were used. No tests were done on disease or insect resistance or susceptibility. No tests were done on cold or drought tolerance. This new variety produces medium sized blooms with white ray florets blooming for a period of 5 weeks.

From the cultivars known to inventor the most similar existing cultivar in comparison to ‘Zanmuglow’ is ‘Zanmuspen’ (U.S. Plant Pat. No. 21,205). When ‘Zanmuspen’ and ‘Zanmuglow’ are being compared the following difference is noticed: plant size of ‘Zanmuspen’ is larger than that of ‘Zanmuglow’.

The following is a description of the plant and characteristics that distinguish ‘Zanmuglow’ as a new and distinct variety.

The color designations are taken from the plant itself. Accordingly, any discrepancies between the color designations and the colors depicted in the photographs are due to photographic tolerances. The color chart used in this description is: The Royal Horticultural Society Colour Chart, edition 2001.
